Application filed December 2, 1914. Serial No. 875,074.

To all whom it may concern Be it known that we, ARTHUR D. ROBIN- SON andALFRED P. BOLLER, Jr., citizens of the United States, and residents,respectively, of the borough of Manhattan, city, county, and State ofNew York, and of East Orange, in the county of Essex and State of NewJersey, have invented certain new and useful Improvements in CollapsibleTripods, of which the following is a specification.

The present invention relates generally to tripods and has moreparticularly reference to tripods which may be used in connection withmoving picture machines.

The main object of the invention is to produce a very substantial andrigid structure which is readily collapsible so as to render it easilyportable.

With these and other objects in view the invention consists of thefeatures of con.- struction, combination of parts and arrangement ofelements as pointed out in the claims appended hereto, a preferredembodiment of which is disclosed in the accompanying specification anddrawings.

In said drawings: Figure 1 is a vertical sectional view, with partsremoved and broken away, through the standard showing the devicecollapsed and the legs nested within the standard. Fig. 2 is afragmentary view, partly broken away, of the stand ard in its workingposition with the legs in place. Fig. 3 is a sectionalplan view withparts broken away, taken on the line 33 of Fig. 2.

1 indicates a hollow standard for suitably supporting a member such asindicated by 2. At the lower end of said standard there is a collar 3provided with a plurality of abutment members 4 having saddle portions 5angularly disposed with respect to the standard. The said collar 3 isprovided with ears 6 for the reception of the pivoted clamping means 7 apivot 8 connecting the ears 6 and the members 7 This pin 8 may be ratherloosely fitting if desired. 9 indicate the legs which are adapted to beinserted in the sockets 10 of the clamping members, said legs being heldin position in said sockets by means of the clamping screw 11. In usethe leg 9 is inserted in the socket portion 10 and secured thereto bymeans of the member 11 and said clamping means 7 is thereafter swungoutwardly until the up- Specification of Letters Patent.

per portion of the leg 9 rests in the saddle portion 5 of the abutmentmember 4:, at which time the said socket member 10 will be substantiallyin alinement with the saddle portion 5. It will be observed that saidabutment member 4 is under compression and said clamping member 7 isunder tension and that the parts are so arranged that the three pointsof support, consisting of the saddle portion 5, the pivot 8 and thesocket portion 10, form the corners of a triangle which may be drawnbetween said points, as indicated in dotted lines, thereby obtaining avery rigid and substantial support.

When the device is collapsed the legs 9 are nested within the hollowstandard 1 and for the purpose of more readily holding said legs inposition within the standard, the clamping member 7 may be provided witha projection 12 which serves to confine said legs within the standardwhen the clamping means are folded back into position as indicated inFig. 1.

What is claimed is:

1. A collapsible tripod comprising: a hollow standard, removable legsadapted to be clamped to the exterior of the standard when in use and tobe nested within the hollow standard when not in use, collapsibleclamping means exterior to said standard for removably securing the legsin position for use, and a projection on said clamping means adaptedwhen the latter are collapsed to confine the legs nested within thestandard.

2. A collapsible tripod comprising: a standard, a plurality of angularlydisposed abutment members on said standard, pivotally supported clampingmembers on said standard below said abutment members, and legs adaptedto be supported by said abutment and clamping members.

3. A collapsible tripod comprising: a standard, a plurality of abutmentmembers each having a saddle angularly disposed with relation to saidstandard, pivotally supported clamping members on said standard belowsaid abutment members each having a socket angularly disposed withrespect to the standard and in alinement with the saddle portion of theabutment members, and legs adapted to be supported by said abutment andclamping members.

4. A collapsible tripod comprising: a standard, a plurality of angularlydisposed abutment members on said standard, pivotally supported clampingmembers on said standard having sockets for the reception of legs belowsaid abutment members, and legs adapted to be supported by said abutmentand clamping members, the abutment member, the socket of the clampingmember and the pivotal support of the clamping member formingsubstantially a triangular support.

Signed at New York city, in the county of 10 New York and State of NewYork, this l ith day of November, A. D. 1914.
